    Default Xuzhu's LDA and damaging capacity

    I found a passage noting what seems to be Xuzhu's first strike after receiving Wuyazi's life force energy (LFE):

    那老人眯着双眼,有气没力的一笑,说道:大功告成了!乖孩儿,你福泽深厚,远过我的期望,你 向这板壁空拍一掌试试!虚竹不明所以,依言虚击一掌,只听得喀喇喇一声响,好好一堵板壁登时垮了半边,比他出全力撞上十下,塌得还要厉害。虚竹惊得呆了,道: 那那是什么缘故? ... 那老者微笑道:你还没学过本门掌法,这时所能使出来的内力,一成也还不到

    Tapping into less than 10% of Wuyazi's internal energy, Xuzhu simply extended his palm out and was already able to break a stone wall with a LDA. The distance wasn't stated, but it was said to be via long distance.

    Imagine if he used 40 times more power, which is what he would have had after transmission from all 3 Xiaoyao Sect elders, since he used less than 10% now!

    This is also interesting b/c in Ode to Gallantry, 5th tier fighters are able to shatter walls with their palm wind. With this current example, this means that the 5th tier OTG'ers could have about 10% of Wuyazi's power.

    With that assumption, let's see how the OTG'ers stack up against the DGSD'ers.

    Ding Busi = 10% of Wuyazi
    Bai Zizai = maybe 20% of Wuyazi
    Pre-island Shi Potian = 3 to 4x Bai Zizai = 60% to 80% of Wuyazi
    Post-island Shi Potian = maybe 2x pre-island Shi Potian = 120% to 140% of Wuyazi

    Of course, those numbers are just speculations, albeit educated ones. Ding Busi could have only 5% of Wuyazi's power, since he performed a similar feat as Xuzhu and Xuzhu used less than 10% of Wuyazi's power (which could be 5%). One thing I am sure though is that pre-island Shi Potian must be at least 3 times better than Bai Zizai.

    This comparison was meant to show that wall-shattering can be done at the sub-sub-Great level in multiple Jin Yong novels.

    板壁 = wooden plank wall

    Its not a stone wall. But since XZ did not know any LDA technique and he was just pushing his palm out and it wasn't even 10% of WYZ's energy and he probably tripled that after the encounter at Xixia, its still amazing.

    But here is more fun with wuxia math! It was said that that strike was more powerful then XZ ramming it 10 times. So if XZ is 60kg and runs at 5m/s (slightly below average for human sprinting), we have a kinetic energy of 0.5 x 60 x 5 x 5 = 750 joules. 10 x that would be 7500 joules.

    So that <10% strike was 7500 joules at minimum.

    What's the implication for that number?

    Hmmm. Ok. Let us lay the assumptions and parameters.

    1 watt = 1 joule per second.

    XZ exerted less than 10% of WYZ's energy. Lets make it 7.5%. Nicely between 'Yi Chen and Ban Chen' (Since WYX did not use Ban Chen).

    Sub-Elite fighters can strike 15-30 times per second (e.g. LHC, XLN). Lets take 20 as a lower average.

    WYZ claimed he transferred 70 years of energy. Lets take it at face value when comparing to TSTL and LQS. TSTL studied from age 6. She was about over 90 when she lost 90% of her energy to XZ. Lets equate TSTL's energy to LQS to keep it simple. So XZ later received : 0.90 x (90-6) x 2 = 151.2 WYZ year energy units (WYZYEU).

    Later, XZ was said to have studied intensively and benefitted _greatly_ from the Ling Jiu manuals. Lets say he got a 20% boost?

    So. We have the final XZ horsepower at 1.2*(70+151.2) = 265.44 WYZYEUs

    7.5% of of 70 WYZYEUs = 7500 joules
    Therefore 1 WYZYEU = 1428.6 joules
    XZ has 265.44 WYZYEUs which = 379,207.6 joules of striking power

    But if he can strike 20 times per second, that means he can generate 379,207.6 x 20 = 7,584,152 watts.

    THEREFORE, Xu Zhu could potentially generate 7.58 megawatts of energy!!!

    If he only strikes twice a second, then it is down to 0.758 megawatts. Still impressive and I am sure these super elites can strike > 2 times a second.

    To put 0.758 megawatts into perspective. The average car 2.0 litre mid size car generates about 100Kw of power. So XZ generates the full horsepower of 7.58 cars!

    WYZ year energy units (WYZYEU).

    Wuyazi gets his own scientific measuring unit.
    Great invention.

    lol

    Maybe you guys should be reading this comic instead. In this comic, the characters' powers are measured in horsepower units. It's a crude but pretty entertaining title.

    Okay this would mean LQS and TSTL will both have stronger internals than WYZ himself, by about 11 extra years each. Seeing how H7G was said to be at quite a significant disadvantage as he fought with OYF as he missed out on TWO years of internal training. this would mean WYZ would be at a huge disadvantage if he fought with either, even if he was not crippled.

    I guess the only reason is that he was crippled thus he could not practice his internal. But the Old Woman under JueQing Valley (forgot her name, Gongsun Zhi's wife)'s internal increased vastly despite being crippled. So it would mean TSTL and LQS were better than WYZ to start with, which i find kind of not right...

    Why did you measure 7.5% of 10% of 70 WYZYEUs = 7500 joules? It should be just 7.5% of 70 WYZYEUs, meaning 100% strike is only 100,000 joules. Assuming its 265.44 years in total, it only amounts to 379200 Joules. Much less than what you shown to be. So it means that XZ can "only" power 7.58 cars

    It was done to keep it simple. I didn't want to guess and assume that WYZ's 70 years => 80 years of TSTL training.

    Yeah you are right. SHould be 7.5%. I double counted that x10.

    Edited the post.

    Yea so i guess the quality factor of the internal kicks in as well...

    But sure its too keep it simple.

    Looking at these equations, I can imagine how freakingly scary Xuzhu is.
